To all whom 'it may concern.

Be it known that I, JOHN EDWARD OGDEN,

a citizen of the United States of America, and a resident ofMountainville, town of Cornwall, Orange County, and State of New York,have invented certain new and useful Improvements in Concrete Inserts,of which the following is a specification, reference being had to theaccompanying drawings, forming a part thereof.

This invention relates toV new and useful improvements in concreteinserts, and its object is to provide a simple and inexpensive devicewhich may be easily embedded in concrete structures during theirformation, which is adapted to receive the head or nut of a bolt, and toprovide for adjustment of the position of the bolt.

These and other objects of the invention will appear in the followingspecilication in which I will describe the invention, the novel featureso-f which wil-l be set forth in appended claims.

Referring to the drawings:

Figure 1 is a sectional elevation of a device of cast metal which ismade .according to and embodies this invention. This is shown in thecondition in which it comes from ythe casting mold.

Figure 2 is a similar section of the same device embedded in co-ncreteshowing the positions which its parts assume when a bolt is beinginserted.

Figure 3 is another sectional elevation of a device of a somewhatmodified form embedded in concrete and with a member secured thereto bya bolt.

Figure 4 is a sectional plan view of the parts' shown in Figure 3.

Figure 5 is a sectional elevation of a device of still further modifiedform showing a bolt being inserted therein.

Like characters of reference designate cnrresponding parts in all thefigures.

10 designates a body the inner wall of which is cylindrical. top, asshown at 11, and is partly closed at the bottom by an inwardly extendingannul-ar flange 12 and has ears 13 and 14 pro'- jecting from it atspaced intervals. The ears 14 are preferably at the lower end of thebody and constructed to form notches 15. 16 is a circular .disk providedwith a slot 17. This disk is of greater diameter than the openingthrough the center of the flange 12 and of less diameter than that ofThis is closed at the,

1919. serial Nq. 308,687.

Lthe inside of the body 10.' In'makinglthe device the disk 16 ispreferably put inside of the core 18 which determines the size and shapeof the inside of the body. l

Before specifically describing the vstructures shown in the otherfigures of the drawings, I will point out the way in which this deviceis used. After the. body is cast the core 18 is broken up and removed.The disk, however, is too large to come out and therefore remainspermanently inside of the body. When a concrete structure is to be madethe device is placed on one of the form boards, and if desired, may bepositioned thereon by tacks driven through the notches 1,5. The concreteis poured over and around the device as shown at 20 so that the insertbecomes a permanent part of the finished structure.

A bolt 21 may now be inserted by pushing the disk upwardly as shown inFigure 2, until its head o-r a nut thereon passes the edge of the diskwhen the latter may fall down on to the fiange 12 with the shank of thebolt extending through the slot 17. This slot is narrower than theheador nut of the bolt so that the bolt will be held by the disk. 1

to amplify the range of adjustment of the bolt. l/Vhen a bolt is in thedesired position, a member 22 may be secured by means of it and a nut23. n

The ears 13 and 14 strengthen the-grasp of the concreteon the device. InFigures 3 and 4 the outer walls off the body 10A are transversely liutedor ribbed as shown in 24 to increase the grip ofthe concrete on thebody.

The body 10B in Figure 5 `is open at the top. When this form is used itis not neces sary to cast the disk 16 in. the body as it may be insertedfrom the top, But in order to prevent` the concrete from entering thebody, when it is poured, it is necessary to provide a. cover 25.Different modifications of structure may be made within the spirit andscope of this invention and I intend no limitations other than thoseimposed by appended claims.

l/Vhat I claim is:

1. The process of forming a concrete insert which comprises embedding 'aload carrying member within a `chamber for-ming core, casting the bodyof the insert-about to leave the loadVcarry-ng member eupported on theflange aforesaid.

2. The process of formlng a concrete 1nsertV Whlch vcornprlses, oa-stlngal` hollow 1n- V sert body about a load carrying element and with aflange to @Online the load ycarrying element Within the chamberof thelnshed 10 insert body. Y

n Witness whereof I hereunto set my hand this 27th day of June, 1919.
